A bridge is primarily constructed to:
Close the path beneath
Improve navigation only
Provide passage over an obstacle without closing the path beneath
Reduce river width
Which component of a bridge retains the approach embankment and transfers load to ground?
Pier
Abutment
Bearing
Girder
The vertical intermediate support between spans is called:
Wing wall
Return wall
Pier
Foundation
The rise in upstream water level caused by a bridge obstruction is termed:
Scour
Freeboard
Afflux
Backwater curve
A bridge with span greater than 120 m is classified as:

Effective waterway is always equal to linear waterway.
True
False
Integral bridges eliminate bearings and expansion joints.
True
False
Assertion (A): Scour depth governs the minimum depth of bridge foundations. Reason (R): Maximum erosion generally occurs near piers and bends of rivers.
A and R are true and R explains A
A and R are true but R does not explain A
A is true but R is false
A is false but R is true
The part of the bridge below bearings is called the (a) .
Bearings allow controlled movement due to (a) changes.
The lowest part of a bridge that transfers loads to soil is the (a) .
The maximum observed flood level is known as (a) .
The vertical clearance between HFL and soffit of deck is called (a) .
